Kickstarter doesn't reflect Paypal numbers, it's another system. Kickstarter doesn't support Paypal. There are currently ~$41k and 950 backers on paypal.

Obsidian was working on a widget for their website that would show both total though. Darren, the webmaster at OE, is unfortunately a really busy soon-to-be-new-daddy man that also have to create an Obsidian store currently.

As for the 2.6mil, the Kickstarter achieved it as well, but RPGCodex removed their 5k reserved spot when it crossed it. They will be pledging through paypal later.
